Number
EGL Extension XXX
Extension Type
EGL display extension
Dependencies
None
Overview
This extension allows the client to create contexts that are internally
virtualized on a single native context for performance or stability.
New Types
None
New Procedures and Functions
None
New Tokens
Accepted as an attribute name in the <attrib_list> argument of
eglCreateContext:
EGL_CONTEXT_VIRTUALIZATION_GROUP_ANGLE 0x3481
Additions to the EGL Specification
None.
New Behavior
To request that a context should be part of a virtualization group,
use the attribute EGL_CONTEXT_VIRTUALIZATION_GROUP_ANGLE. EGL_DONT_CARE
can be used to allow the implementation to decide what virtualization
group is used. The default value of EGL_CONTEXT_VIRTUALIZATION_GROUP_ANGLE
is EGL_DONT_CARE. It is undefined behaviour to have multiple contexts from
the same virtualization group current different threads simultaneously.
Issues
None
